IFOPT (''Identification of Fixed Objects in Public Transport'') is a prCEN Technical Specification that provides a Reference Data Model for describing the main fixed objects required for public access to Public transport, that is to say Transportation hubs (such as airports, stations, bus stops, ports, and other destination places and points of interest, as well as their entrances, platforms, concourses, internal spaces, equipment, facilities, accessibility etc.). Such a model is a fundamental component of the modern Public transport information systems needed both to operate Public transport and to inform passengers about services. ==Scope == IFOPT is itself built upon the CEN Transmodel standard and defines four related sub models. * ''Stop Place Model:'' Describes the detailed structure of a Stop Place (that is stations, airports, ferry ports, bus stops, coach stations, etc., providing a point of access to public transport) including Entrances, pathways, and accessibility limitations. * ''Point of Interest Model:'' Describes the structure of a point of interest (that is tourist attractions, leisure facilities, stadia, public buildings, parks, prisons, etc.) to which people may wish to travel by public transport) including physical points of access, i.e. Entrances. * ''Gazetteer Topographical Model:'' Provides a topographical representation of the settlements (cities, towns, villages etc.) between which people travel. It is used to associate Stop and Station elements with the appropriate topographic names and concepts to support the functions of journey planning, stop finding, etc. * ''Administrative Model.'' Provides an organisational model for assigning responsibility to create and maintain data as a collaborative process involving distributed stakeholders. Includes namespace management to manage the decentralised issuing of unique identifiers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Identification of Fixed Objects in Public Transport」の詳細全文を読む スポンサード リンク
